The Peace River Formation is a stratigraphical unit of middle Albian age in the Western Canadian Sedimentary Basin.

The Peace River Formation consists of greywacke, coal, coarse to fine marine sandstone and dark, fissile, non-calcareous shale.

The Peace River Lowland, a landform region in the Alberta Plateau, is a gently rolling lowland without clearly defined outer boundaries extending east of the Rocky Mountains on both sides of the Peace River and sloping downward to the north and east.

The higher hills in the foothills east of the Rockies in northeastern British Columbia have elevations of about 1000 m and the plains west of Lake Athabasca are about 300 m above sea level.

[2] The lowland's Quaternary sediments of the former lake bottom of Glacial Lake Peace are underlain by Upper and Lower Cretaceous sedimentary rocks mainly shales of the Shaftesbury formation and sandstones of the Dunvegan and Peace River formations.
